01 / 05 · What it measures
Crowd pressure on the barrier line
The Barrier Load Monitor System measures the pressure at the barrier itself, where the crowd meets the line.

Features
Barrier load monitoring in real time
02 / 05 · Sensor barrier
No extra barrier elements
The sensors are integrated into the Straight Section, so the measuring points become part of the barrier line. No extra barrier elements are added to the layout.

Data and graphics during the event
The sensors are linked to computers at the event. Mojo Barriers’ own software shows the readings in real time as data and graphics, so hotspots can be spotted and handled as they develop.
04 / 05 · Layout
Side by side or spread along the line
Sensor barriers can stand side by side for continuous coverage or be spread as single measuring points along the whole barrier line.
05 / 05 · After the event
Recorded for analysis
The readings are recorded for later analysis and research purposes. Detailed reports after data analysis are optional.

FAQ
Questions about the BLMS
Two contacts, depending on the question:
- Measuring points for your layout and hire: the rental company in your country
- Data sheets and product information: Mojo Barriers BV, by phone or email
Barrier load monitoring means measuring how much pressure a crowd puts on a temporary barrier line, for example in front of a stage, while the event is running. The readings show where pressure is building up and where peaks occur along the line. With Mojo Barriers, this is the Barrier Load Monitor System (BLMS), part of the barrier systems range.
- security staff during the event, as an additional information channel
- police
- promoters
- planners after the event, as feedback to improve barrier layouts and site plans for the next event

- where along the barrier line pressure should be measured
- continuous coverage or single measuring points
- the number of sensor barriers, with up to 10 per controller
- power requirements: a 24 V supply for each controller
- who watches the readings during the event
- whether a detailed report is needed after the event
The BLMS measures pressure on the barrier, not the number of people or their density. It shows how much load is applied to particular sections of the barrier line, read from the sensor barriers in that line, rather than a calculated uniformly distributed load or point load. Counting people or measuring crowd density across areas needs other tools.
